Front

What does PEMDAS stand for?

Back

PEMDAS stands for Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). It is the order of operations used in mathematics.

Front

What is the first step in the order of operations?

Back

The first step is to solve anything inside Parentheses.

Front

What is the second step in the order of operations?

Back

The second step is to evaluate Exponents.

Front

What is the third step in the order of operations?

Back

The third step is to perform Multiplication and Division from left to right.

Front

What is the fourth step in the order of operations?

Back

The fourth step is to perform Addition and Subtraction from left to right.

Front

Simplify: 2 + 3 × 4

Back

14 (First, multiply 3 × 4 = 12, then add 2 + 12 = 14).

Front

Simplify: (5 + 3)²

Back

64 (First, add 5 + 3 = 8, then square it: 8² = 64).

Front

What is an exponent?

Back

An exponent is a number that shows how many times to use the base in a multiplication. For example, 2³ means 2 × 2 × 2.

Front

What is the value of 3²?

Back

9 (3² means 3 × 3 = 9).

Front

What is the value of 4 + 2 × 3?

Back

10 (First, multiply 2 × 3 = 6, then add 4 + 6 = 10).
